Strap for Pilot's Watch Chronograph Stainless Steel / Black / Italian / Strap

The lug width of the IWC Pilot IW3706-02 is 20mm. This measurement is taken by positioning a digital calliper between the internal lugs. It is important not to confuse lug width with the external width of the case, which is slightly larger.

The best strap depends on usage and style preference. For formal aesthetics, we recommend dark brown or black alligator. For everyday versatility, calf leather with vegetable tanning develops a natural patina over time. For authentic avionic style, a navy NATO or structured black rubber are choices that respect the watch's character.

Strap replacement is performed using a spring bar removal tool or small flat file. Position the tool under the internal lug pin, gently lever to release the spring, then slide the pin out of the lug hole. Reverse the procedure to install the new strap, ensuring the pin is firmly seated on both sides.

No, if made from noble materials by specialist craftsmen. A strap in alligator, vegetable-tanned calf, or technical rubber does not compromise value if removable. Indeed, a personalised strap is often appreciated by collectors, as the watch remains original and the strap can be changed according to context.

Durability depends on material and use. Alligator or vegetable-tanned calf lasts 3-5 years with daily wear, developing a patina that enhances appearance. Rubber resists 2-3 years before losing elasticity. Casati Milano straps carry an 18-month guarantee and can be refurbished through professional restoration to extend lifespan.
